Genetics
Research indicates that common personality traits associated with narcissistic personality disorder, such as grandiosity and entitlement, may be passed down from older generations. Although their diagnosis of narcissistic personality disorder may raise the likelihood that their children will acquire it, parents with NPD are unlikely to pass these traits on to the next generation.
Additionally, some people are probably genetically predisposed to NPD. Even though they might not go on to exhibit narcissistic traits, exposure to specific risk factors may put them at higher risk for NPD.
Have you ever met a narcissist, or worse, were you somehow involved with one? If so, then you’re probably stronger than you thought you were. Narcissists are so manipulative they can easily damage your mental health without you even noticing it.
However, if you’re still stuck with that person and going to therapy isn’t fit for you or your finances at this moment, then you may want to check out the book How to Handle a Narcissist: Understanding and Dealing with a Range of Narcissistic Personalities.
Written after years of research on this topic, this guide might be able to help you understand this condition better and, more importantly, how to get over a failed relationship with a narcissist. The book is available on Amazon at this link.
Molecular imbalance
Another root cause of narcissistic personality disorder may be a molecular imbalance that can strain the body. Scientists say that various brain scans show that people who suffer from this condition have less gray matter in that part of the brain that shows empathy. Now it all makes sense, right?
Neuroscientists have also discovered a connection between differences in prefrontal brain structure and NPD. In the future, it may be possible to identify narcissistic personality traits simply by examining a person’s brain, but more research is needed.
So that means that we could go to the doctor with our partner for a regular checkup and ask for a brain scan too? Would be easier for sure! Then probably a lot of people would break up with the narcissist right away.
According to some researchers, physical characteristics or appearance may even play a role in NPD. Strength, physical attractiveness, and athletic prowess are all linked to higher narcissistic traits. After all, a person’s appearance is just one of many factors that are thought to influence their personality.
